MDT technologies Schaltaktor 12-fach, 12TE, REG AMS-1216.03 (AMS-1216.03)

12-channel KNX switching actuator with 16 A per channel, DIN rail mount, 12 TE width.

Overview

The MDT AMS-1216.03 is a 12-fold switching actuator for KNX bus systems. It provides 12 potential-free normally open contacts, each rated for 16 A resistive, inductive, and capacitive loads. The device is designed for DIN rail mounting (REG) and occupies 12 TE (module widths) in the distribution board. Manual operation is possible via push buttons on the front, with LED status indication per channel. The actuator supports scene control, logic functions, time functions such as staircase lighting, and central functions. It is powered by the KNX bus voltage (21-30 V DC) and is compatible with ETS5 or higher for configuration and firmware updates.

What stands out

• 12 independent switching channels, each 16 A
• Manual override with push buttons and LED status
